IMPROVEMENT IN STEAllrI-IENGINE LUBRIGATORS.

TO ALL WHOM IT MAY CONCERN..

Be it known that I, JOSEPH COLLETT, of Williamsburg, in the county of Kings, and Sta-te of New York, have invented a certain new and useful Improvement on Lubricators, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying` drawing, forming part of this specication, and in which` I l Figure 1 represents a front elevation of a lubricator constructed according to my improvement, and

Figure 2 a'vertical section thereof, viewed at right angles to fig.

Like letters of reference indicate corresponding parts throughout both figures. v

My invention is applicable to various parts of engines or machinery in which the lubricating material or fluid has to be introduced to the parts to be lubricated against pressure. as of steam for instance, or wherever the normal pressure on the lubricating material in the 'reservoir of the lubricator differs from the pressure to which it is exposed at its discharge aperture. It will be sufiicient here, however, to explain my invention, to describe it as a lubricator to an engine steam-'chest or valve-chamber, and in this connection the nature of my invention consists, rst, in a novel tubular construction of the interior of the lubricator, connecting the upper and lower -portions thereof,'so as to form asteam passage between the upper part vof the reservoir and lubricating discharge-chamber, with a.` separate passage for the grease to the latter, and independent valves to the steam passage at top' and grease passage below, whereby not only may a balance of pressure be produced-abovc/afv/ below the lubricating material, but on opening the lubricator Ato the atmosphere both the escape of steam and discharge of grease are or 'may be automatically prevented, and. this without disturbing the gauge or tap thatregulates the discharge of grease when the lubricator is closed; Aand my invention further consists in so com- `bining the stopper or cover of the reservoir with the valve to the steam-way that connects the upper and lower portions of the lubricator as that closing the stopper or cover opens said valve, which closes by the pressure of steam assaid stopper is opened; and said invention further consists in a combination, with a general greasedischarge valve that -opens and closes accordingly as pressure is thrown on or removed from it, of a separate l regulating valve thatmay be worked by hand to open, adjust, or shut off the discharge of grease from the lubricator.

Referring to the accompanying drawing, A represents the reservoir of the lubricntor into-which the lubri- 'cating material may be inserted by an opening at its top, covered by a screw-stopper, B, or other suitable cover. C is the nozzle or discharge end that may be formed with a discharge-chamber, a, and delivery-aperture, b, and that may be connected to the reservoir A by an intermediate piece or connection, B, on to which the nozzle C and reservoir are screwed, the one above and the other below. This connection, D, has a vertical upward extension, E` terminating in a valve-seat, F, and which is formed with a passage, c c, running up through it and downwardlythrough the body of the connection so as to establisli'communication between the reservoir at ornear its top and the discharge-chamber a. Said connection D also is made with a lateral arm, G, and with passages, d ef, the rst'one of which (d) runs longitudinally through the arm G, and at its inner extremity is-'madc to form a valve-seat, so Aas, by the actionpof a4 screw-valve, H, to open or shut oif communication between the other two passages (e and f) that connect, the one, e, with the reservoir, and the other,f, with the discharge-Chambord, and which latter passage, f, is opened or closed at its bottom by a loose valve, I, as the valve-seat F of the extension E is also opened or closed by a loose valve, J. The object of the valve H is to open or shut off or to regulate at pleasure the discharge of grease, and, by way of determining the amount of discharge, or giving it a fixed quantity, variable at pleasure, I mark on the face of the wheel g, by which thc valve is operated, divisions or lines that, a'ccordingly'as they are made to change their position relatively to any fixed point, serve toshow the amount of discharge taking place. Now, supposing the lubricator to be fixed in its place on a steam-chest or valve-chamber, and to be supplied witha proper quantity of grease, and the regulating valve H to be partially open, then it.will be evident that steam entering bythe aperture b into the chamber a uds its way by the passage c c and valve-seat F into the reservoir A above the surface of the grease, and thus a pressure from above is induced equal to that acting from beneath on thc grease in the passage f, thereby producing a counterbalance which permits of the free discharge of the grease, as regulated by the sorew-valve H. The valve I, under this conditionofthings, remains open, as shown in the drawing, permitting of the softened or meltel -grease to pass Vbeneath it, through side orifices in its bottom, into the aperture b, while the upper valve J is kept' open by the screw-stopper. But supposing it to be desired, either for the purpose 0F putting fresh lubricating mattei' into the reservoir, or for any other reason, to open the lubricator while the engine is at work, then, on taking oli the stopper or cover B, steam rushing up the passage c c closes the valve J, and accordingly prevents that escape which otherwise would take place, and which involves not only waste of Steam but also interference with resupplying the reservoir. Furthermore, the reservoir A being thus freed from steam, the pressure from below closes the valve I against its seat in the passagef, thereby preventing the grease from being blown out; and this, it will be seen, is e'ected without of necessity closing the regulatingvalve H or its adjustment to give a 'fixed discharge on closing again the cover or stopper B. Still it is not necessary, to shut off the discharge of'grease, that the stopper B,sl1ould be removed, as it may bedone by closing the valve. lI. Y

This combination of an automatic and hand control ofthe lubrioator will be found serviceable in numerous instances. Oi course the shape or disposition of the several passages and forms of valves may be variously modified without departing from the principle of my invention.

1. The combination of the.steamway or passage@ c and grease passage or passages e'f, with their valves I J, arranged for action, in connection with the reservoir and grease outlet or discharge-chamber, substantially as specified.

2. The valve J to the steam-Weyer passage that admits steam to the upper portion of the reservoir, in combination with the stopper or cover to the lubricatcr, so arranged in relation thereto that said cover on being shut uncloses and retains open the valve, essentially as and for the purpose herein set forth'.

l 3. In combination with the grease-discharge valve I, that closes by the action of the steam, the handdjustable valve Ll, for joint or separate action as herein set forth.
